Meta Quest 3S stuck in boot loop after update – factory reset fails

I’m experiencing a critical issue with my Meta Quest 3S after installing an official system update.

The device is now stuck in a boot loop and cannot start normally. I attempted to perform a factory reset through the boot menu, but it fails with an error. Currently, I only have access to the boot menu, and no other recovery options seem to work.

Here is a summary of the issue:

- Boot loop after official update

- Factory reset fails with an error

- Only boot menu is accessible

Reinstall attempts did not resolve the issue

I can provide photos or additional details if needed.
Thank you.
